Should I sell on gronk?

I trusted bucs qbs in my league and I’m trying to hold onto my playoff spot as the 4th seed. I was offered Russ for Gronk and also Rivers for Flash Gordon. I have burton as my back up TE then cooks,sanders, diggs and Landry as my other WR. Any help would be great!! Also my other streaming options are Super limited bc everyone in my league is a megala-douche and took every viable option. :face_with_symbols_over_mouth:
